Digital BW, The Print

Hi Steve,

None of my QTR profiles use MIS LK. I've tried the following:

Warm profile:
- MIS UT7-C
- MIS UT7-LC

Cool profile:
- MIS UT7-M
- MIS UT7-LM

PKN neutral:
- MIS PKN
- MIS UT7-LK (LKN)

PKN cool:
- MIS PKN
- MIS UT7-M

All of the profiles use 100% GLOP in the Y position.

I see the same behaviour in all the profiles - I have to run the GLOP 
full strength at 100% to get rid of all the bronzing.

The first two profiles also exhibited significant mottling in the 
shadows with the GLOP at this strength. I had to go down to 50-60% to 
get rid of the mottling, but then the bronzing was back.

I also tried a reverse curve for the GLOP where it ran at 50% at a 
straight line from 0-50% and then gradually increased to full strength 
at 100% white. This got rid of some of the mottling but didn't remove 
all of the bronzing.

I see Carl's profiles consistently go straight from PK and PKN to the 
lighter gray and toner inks from the UT7 inkset while he skips the 
darker ones. I will try the same and see if that helps.
